rtlwifi: Remove some redundant code
The symbol DBG_EMERG is no longer used and is removed.
In a number of places, the code has redundant messages. For example, if
the failure for the firmware to run is logged, it is not necessary to

the value based our hardware TX capabilities as some chips can not send
more than 16kB (factor 1). Limit for all chips is currently 32kB

Since MAX_LEN_CFG_MAX_PSDU is global setting, on multi stations modes

not set bigger value to speed up communication with some stations and

====================
MV88E6390 batch two
This is the second batch of patches adding support for the
MV88e6390. They are not sufficient to make it work properly.
The mv88e6390 has a much expanded set of priority maps. Refactor the
existing code, and implement basic support for the new device.
Similarly, the monitor control register has been reworked.
The mv88e6390 has something odd in its EDSA tagging implementation,
which means it is not possible to use it. So we need to use DSA
tagging. This is the first device with EDSA support where we need to
use DSA, and the code does not support this. So two patches refactor
the existing code. The two different register definitions are
separated out, and using DSA on an EDSA capable device is added.

====================
ipv4: fib: Replay events when registering FIB notifier
Ido says:
In kernel 4.9 the switchdev-specific FIB offload mechanism was replaced
by a new FIB notification chain to which modules could register in order
to be notified about the addition and deletion of FIB entries. The
motivation for this change was that switchdev drivers need to be able to
reflect the entire FIB table and not only FIBs configured on top of the
port netdevs themselves. This is useful in case of in-band management.
The fundamental problem with this approach is that upon registration
listeners lose all the information previously sent in the chain and
thus have an incomplete view of the FIB tables, which can result in
packet loss. This patchset fixes that by dumping the FIB tables and
replaying notifications previously sent in the chain for the registered
notification block.
The entire dump process is done under RCU and thus the FIB notification
chain is converted to be atomic. The listeners are modified accordingly.
This is done in the first eight patches.
The ninth patch adds a change sequence counter to ensure the integrity
of the FIB dump. The last patch adds the dump itself to the FIB chain
registration function and modifies existing listeners to pass a callback
to be executed in case dump was inconsistent.
---
v3->v4:
- Register the notification block after the dump and protect it using
the change sequence counter (Hannes Frederic Sowa).
- Since we now integrate the dump into the registration function, drop
the sysctl to set maximum number of retries and instead set it to a
fixed number. Lets see if it's really a problem before adding something
we can never remove.
- For the same reason, dump FIB tables for all net namespaces.
- Add a comment regarding guarantees provided by mutex semantics.
v2->v3:
- Add sysctl to set the number of FIB dump retries (Hannes Frederic Sowa).
- Read the sequence counter under RTNL to ensure synchronization
between the dump process and other processes changing the routing
tables (Hannes Frederic Sowa).
- Pass a callback to the dump function to be executed prior to a retry.
- Limit the dump to a single net namespace.
v1->v2:
- Add a sequence counter to ensure the integrity of the FIB dump
(David S. Miller, Hannes Frederic Sowa).
- Protect notifications from re-ordering in listeners by using an
ordered workqueue (Hannes Frederic Sowa).
- Introduce fib_info_hold() (Jiri Pirko).
- Relieve rocker from the need to invoke the FIB dump by registering
to the FIB notification chain prior to ports creation.

ipv4: fib: Replay events when registering FIB notifier
Commit
b90eb7549499 ("fib: introduce FIB notification infrastructure")
introduced a new notification chain to notify listeners (f.e., switchdev
drivers) about addition and deletion of routes.
However, upon registration to the chain the FIB tables can already be
populated, which means potential listeners will have an incomplete view
of the tables.
Solve that by dumping the FIB tables and replaying the events to the
passed notification block. The dump itself is done using RCU in order
not to starve consumers that need RTNL to make progress.
The integrity of the dump is ensured by reading the FIB change sequence
counter before and after the dump under RTNL. This allows us to avoid
the problematic situation in which the dumping process sends a ENTRY_ADD
notification following ENTRY_DEL generated by another process holding
RTNL.
Callers of the registration function may pass a callback that is
executed in case the dump was inconsistent with current FIB tables.
The number of retries until a consistent dump is achieved is set to a
fixed number to prevent callers from looping for long periods of time.
In case current limit proves to be problematic in the future, it can be
easily converted to be configurable using a sysctl.

ipv4: fib: Allow for consistent FIB dumping
The next patch will enable listeners of the FIB notification chain to
request a dump of the FIB tables. However, since RTNL isn't taken during
the dump, it's possible for the FIB tables to change mid-dump, which
will result in inconsistency between the listener's table and the
kernel's.
Allow listeners to know about changes that occurred mid-dump, by adding
a change sequence counter to each net namespace. The counter is
incremented just before a notification is sent in the FIB chain.

Alex provides changes so that we are much more robust about defining what
we can and cannot offload in i40e and i40evf by doing additional checks
other than L4 tunnel header length.
Jake provides several fixes/changes, first cleaning up a label that is
unnecessary, as well as cleaned up the use of a "magic number". Clarified
the code by separating the global private flags and the regular private
flags per interface into two arrays, so that future additions will not
produce duplication and buggy code. Adds additional checks to protect
against NULL values for msix_entries and q_vectors pointers.
Michal adds Clause22 method for accessing registers for some external
PHYs.
Piotr adds additional protocol support for the admin queue discover
capabilities function.
Tushar Dave fixes a panic seen on SPARC, where writel() should not be
used to write directly to a memory address but only to a memory mapped
I/O address otherwise it causes data access exceptions.
Joe Perches separates out a section of code into its own function, to
help reduce i40evf_reset_task() a bit.
Alan fixes an issue by checking for NULL before dereferencing msix_entries
and returning early in the case where it is NULL within the i40evf_close()
code path.
Henry provides code cleanup to remove unreachable and redundant sections
of code. Fixed up an issue where new NICs were not identifying "unknown
PHYs" correctly.
Harshitha fixes a issue where the ethtool "Supported Link" modes list
backplane interfaces on X722 devices for 10 GbE with SFP+ and Cortina
retimer, where these interfaces should not be visible to the user since
they cannot use them.

Namely, overlaying allocation of pointer array and fixed part of

Well, you need quite specific set of conditions:
*) race window opens once per pernet subsystem addition
(read: modprobe or boot)
*) not every pernet subsystem is eligible (need ->id and ->size)
*) not every pernet subsystem is vulnerable (need incorrect or absense
of ordering of register_pernet_sybsys() and actually using net_generic())
*) to hide the bug even more, default is to preallocate 13 pointers which
is actually quite a lot. You need IPv6, netfilter, bridging etc together

Merge git://git./linux/kernel/git/davem/net
Couple conflicts resolved here:
1) In the MACB driver, a bug fix to properly initialize the
RX tail pointer properly overlapped with some changes
to support variable sized rings.
2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
overlapping with a reorganization of the driver to support
ACPI, OF, as well as PCI variants of the chip.
3) In 'net' we had several probe error path bug fixes to the
stmmac driver, meanwhile a lot of this code was cleaned up
and reorganized in 'net-next'.
4) The cls_flower classifier obtained a helper function in
'net-next' called __fl_delete() and this overlapped with
Daniel Borkamann's bug fix to use RCU for object destruction
in 'net'. It also overlapped with Jiri's change to guard
the rhashtable_remove_fast() call with a check against
tc_skip_sw().
5) In mlx4, a revert bug fix in 'net' overlapped with some
unrelated changes in 'net-next'.
6) In geneve, a stale header pointer after pskb_expand_head()
bug fix in 'net' overlapped with a large reorganization of
the same code in 'net-next'. Since the 'net-next' code no
longer had the bug in question, there was nothing to do
other than to simply take the 'net-next' hunks.

i40e: set broadcast promiscuous mode for each active VLAN
A previous workaround added to ensure receipt of all broadcast frames
incorrectly set the broadcast promiscuous mode unconditionally
regardless of active VLAN status.
Replace this partial workaround with a complete solution that sets the
broadcast promiscuous filters in i40e_sync_vsi_filters. This new method
sets the promiscuous mode based on when broadcast filters are added or
removed.
I40E_VLAN_ANY will request a broadcast filter for all VLANs, (as we're
in untagged mode) while a broadcast filter on a specific VLAN will only
request broadcast for that VLAN.
Thus, we restore addition of broadcast filter to the array, but we add
special handling for these such that they enable the broadcast
promiscuous mode instead of being sent as regular filters.
The end result is that we will correctly receive all broadcast packets
(even those with a *source* address equal to the broadcast address) but
will not receive packets for which we don't have an active VLAN filter.
